Pick me for Park Ranger

The Brisbane botany student is one of 25 shortlisted candidates for Queensland Park Ranger in Tourism Australia's latest 'Best Job In The World' campaign.

This year there's more than just one job up for grabs; candidates from across the world have been trying send their 'pick me' video auditions viral for six jobs which include titles like 'Chief Funster'.

Making into the top picks from 45,000 applicants Christopher says entering the race for the highly publicised Park Ranger job was more of a calling than a choice.

"I studied Ecology and Plant Science at University of Queensland, and I've lived all over the state, so I know a lot of the National Parks and State Forests.

"Now I work as an ecologist and a botanist and I'd love to share more of my passions - than do the technical stuff."

The six-month, $100,000 role, would see Christopher "checking water temperatures, patrolling the beaches and leaving only footprints", while exploring the state's natural attractions and reporting back to a global audience.

"It'll be a lot of travel and writing - and really pushing for young people to travel Australia and work here.

"I've been all over Facebook, Twitter and Instagram; my take on it is showing outsiders a different aspect of Queensland's National Parks. Everyone knows all the iconic Australian National Parks and animals - so I want to take a different angle to it."

He says he been going to extreme lengths to prove he's got what it takes to bring people to visit Queensland's natural wonders.

"The brief for us to prove ourselves [fit for the role] has been very open to interpretation.

"Today I'm doing a day in the life of a Zoo Keeper - I'm feeding wombats, training dingoes, raking poo," he laughs.

"On the weekend I climbed a 60 metre Eucalypt tree and sleep at the top, and for me that was a different perspective," he says.

Christopher says the competition for the gig is fierce, with just four other Aussies in the running for Park Ranger.

"All the Aussies are Queenslanders; it's kind of our backyard, so who better to promote Queensland parks than someone who knows them.

"I think it would be good [to have an Australian] in the job."

The contestants will spent the next few days trying to drum up interest in their individual campaigns for the job on social media and their blogs.

Christopher is holding out for May 15 when he will find out if he's been selected in the top three.
